Crossbar / handles diameter
The convenience of the grip primarily depends on the diameter of the crossbar (for the horizontal bar) or handles (for the parallel bars). Since the size of the hand can vary significantly from person to person, then the selection for this parameter should be carried out carefully. After all, a too-thick horizontal bar will not be convenient to cover with a small hand or, for example, teenagers, as well as a too-thin one will cause a lot of discomfort for owners of a large, more “adult” palm.
Dimensions
The dimensions of the equipment in the assembled and ready-to-work state. It is important to note that more space is needed for the comfortable and proper usage of the device. This is due to the need to have space for the athlete himself, and the space for arms and legs when performing exercises and using additional equipment. If we are talking about a gym, then people training nearby or placed equipment, etc., can become an obstacle. Therefore, it is recommended when choosing to calculate that in addition to the dimensions of the device, you may need an additional metre of free space on each side.
